Robert Adams ee7cda261c BulletSim: move a bunch of common logic out of BSPrim and BSCharacter
and into the parent class BSPhysObject.
Rework collision logic to enable extra collision after done colliding.
Rename 'Scene' to 'PhysicsScene' to differentiate it from the simulator 'Scene'.

Robert Adams f0a098924e BulletSim: set all linkset objects center of mass to the whole linkset's center of mass 2012-09-15 15:31:49 -07:00
Robert Adams 7c347f4c5c BulletSim: Add calls to linkset class when object going static or dynamic.
Reset center of mass on an object when going dynamic.

Robert Adams 2c5ff93990 BulletSim: Way too many changes in one commit.
Many changes to BSDynamic for readability and commentary.
Linkset hacking for vehicles: don't over mass the root prim.
Add parameter for link constraint solver iterations.
Correct uses of timestep in timescale calculations for vehicles.
Reorganize code/logic for making objects static and dynamic for readability
    and use of API2.
Changed most calls in BSPrim to use API2 calls (the new way).
Avatars do not generate default Bullet collision events but do call up
    to the simulator for every avatar. Reduces overhead.
Objects added to collision list only if they are processing collisions.
    Reduces overhead especially for large numbers of avatars.
Generalize call for water height to GetWaterHeightAtXYZ().
Catch and correct exception getting terrain height when out of bounds.
Correct race condition in Terrain Manager where creation wasn't at taint-time.
Add API calls for constructing compound shapes.
Move NeedsMeshing() logic into object class.
Reorganize logic for object meshing to reduce rebuilding of meshs/hulls.

Robert Adams 126eae7100 BulletSim: Add Bullet body and shape to BSPhysObject and rename
'Body' to 'BSBody' for disambiguation when reading code.
Complete the API2 interface so nearly all methods on bullet
    classes are available to the managed code. The efficient
    single call simulation step is kept in place while all
    other creation/destruction/parameterization can be done
    in the managed code.

Robert Adams 3c097cb7a9 BulletSim: Add some comments (gasp) and log messages. 2012-09-07 16:05:22 -07:00
Robert Adams 7b6987ce83 BulletSim: unify physical objects under BSPhysObjects. Now BSScene and BSLinkset only know of BSPhysObject's and there is only one list to search in BSScene. 2012-08-31 11:41:12 -07:00
Robert Adams 03d76e9403 BulletSim: restore most of the Detail logging statements. Will have
no effect on non-logging running.
Capture region name that is passed to the physics engine and use
    it for detail logging file name prefix.
Fix problem with avatars dropping when flying across region boundries.

Robert Adams ccc69d66a1 BulletSim: add parameters and functionality to specify the mesh
level of detail for large meshes.
Remove parameter and code for DetailLog (conditional logging into
   regular log file).

Robert Adams 376441e550 BulletSim: make it so objects in a linkset do not generate collisions with each other. 2012-08-15 16:29:50 -07:00
Robert Adams 9efe7bf7ba BulletSim: add locking to constraintCollection and rename some of the public method variables to reduce confusion between a physics scene and the real scene. 2012-08-15 12:08:17 -07:00
Robert Adams 0c7ce4fc98 BulletSim: many, many detailed logging messages for physical linkset
debugging.
Linkset bugs fixed where accounting of children would get lost.
Moved scene based vehicle tracking logic from prim to the scene.
Added GetCollisionFlags2 method to BulletSimAPI.
Updated DLLs and SOs.

Robert Adams 3ca770cd2c BulletSim: Add module names to DetailLog output. Fix some problems with linksets that were caused by checking data structures that are changed regularly from taint time code -- resulted in linksets not being unlinked properly. 2012-08-10 08:33:09 -07:00
Robert Adams 320982cae3 BulletSim: add an identifier to the TaintObject call so exceptions that happen when the taint is invoked can be debugged 2012-08-09 15:17:19 -07:00
Robert Adams 38e79b80a8 BulletSim: separate out the constraints by type. The linksets use
6dof constraint but eventually others will be exposed so future
features can use all the Bullet capabilities.
Force children to generate a position update when unlinked.

Robert Adams 5ab151c2d6 BulletSim: add avatar code to keep avatars from ending up trapped under the terrain 2012-08-08 13:48:49 -07:00
Robert Adams 50dbb9ffe4 BulletSim: add parameters and API calls for setting ERP and CFM.
Set ERP and CFM in linkset constraints.
Reorder rebuilding of object bodies so they are not rebuilt everytime
   something is linked and unlinked.

Robert Adams ce812c88cc BulletSim: fix a recursive loop when fetching the mass of the root of a linkset. 2012-07-26 16:06:00 -07:00
Robert Adams 7d30637d51 BulletSim: refactor all the linkset logic out of the prim class
and into its own class. The BulletSim data structures track
individual prims as linksets of 1 so most of the prim code is not
different between a linked and unlinked object.
